Tagli-whom@ may concern:

Be it known that ll, @Hannes L. Benner, av citizen of the UnitedStates, residing at Chicago, countyof Cook, State of illinois, have invented certain new and useiullm- Driers, of which the 'following is a specihcation.

rlhis invention.v relates to improvements in laundry driers. f

rlhe main objects of this invention are: First, to provide Aan improved laundry drier'by means ol which laundry ma be quickly dried and treatedvvith fresh coldv air or air .having therein v.aipurifying, deodorizing, disinfectingv or periuming agent, as may be desired.

Second, fto .provide an improved laundry drier which is of very large capacity and one by means ofwhich the clothes areA lett in a dufly and unwrinlrled condition, Iit being possible to evenly 'drythe clothes to the desiredcondition for ironing or dry them completely',` as may be` desired.

Third, to providean improved laundry drier which is edective for drying laundry as it comes lfrom the'washing machines or with the water partially extracted, as by means ci a centrifugal extractor.

Fourth, tofprovide an improved laundry drier which is very simpleand compact in structure.

VFurther objects, and objects relating to structurel details, will definitely appear from the detailed description to Alollovv.

laccomplish the objects of my l invention by. the devices .and means described in the following specification. The invention is clearly defined and pointed out inthe claims. 'A structure Awhich is a preferred embodiment ol my invention is clearly illustrated in the accompanying drawing, forming a part of this. application, in which:

Fig. l is a detail iront gie unit drier embodyingthe Vfeatures of my invention no attem thavin lbeen' made to.

maintain the proper relative proportion of the parts and. certain parts being shown conventionally and certain "pipes-.I or eonduits 1 being partiallyfbrokenawey: l Fig. lll is a fraentary viefw--partiallyin vertical section on aline corresponding' to' line 2-2 ofFig. lill.'

Fig. .lill is a fragmentary-liront'elevation of a grou or series of 'the driers. Fig. l. is an enlarged detail-elevatio elevation of a sinofthe air shutter actuating means, the parts being shown -in one position by lull lines andv at the eXtreme of its movement the piston is vshown in either direction by dotted lines. zFig. V is an .enlarged detail section through the cylinder control valve.

Fig. Vl is adetail section on a line correspondingto line 6-6 of Fig. ll, showing details of the air control shutter.

Fig. Vllll is a detail side view of a modiiied iorn of my improvements in which the air heating chamber is separate Jfrom the drying chamber.

ln the drawing, similar reference characters Vrefer to similar parts throughout the several views, and the sectional views. are taken looking in the direction el the little arrows at the endsV oi the section lines.

v Referring to the drawing, l provide a dryingV chamber l, prelerablyin' the shape of 'an inverted cone or expanding upwardly from. thev inlet opening 2 at the bottom thereof. rllhis inlet opening lis provided with a screen 3. At its upper end the chamber -is provided with a screened discharge opening 4 with a discharge conduit 5, preierably leading out 'ci the building in which the drier. is installed.

rlhe drying chamber is surrounded with yan air heating' chamber o having a spiral partition 7. therein providing a spiral pasv sage 8, the air inlet pipe 9- being connected to the upper end of this passage, there preferably being a screen' l0 to screen the dirt and dust from the airmThis air inlet prelprovided vfor admitting cold air totheblovverso that coldv air erV warrn. .air or air tempered as desired maya-be delivered to .the

'drying chamber. ll alsolpreferably provide means for vsupplying a disinitectin'ggas or .the lile or ozone .or a deodorizing or perturning agent, therebeing a pair or' tanks i7,

shovvngconventionally in Fig. l, connected pipes l.

erably leads to theoutside of. the building or lll@ ice

- through the other side of the screen and giving the articles more or less of a rotary movement within the drier, the movement being changed by the shifting of the shutter to close off the other side of the screen.y

This is found to add verymaterially to the drying capacity and the clothes come from the drier in a very satisfactory condition, uniformly dry and without wrinkles or creases, the drying being very similar to open air drying, the passing of the' fresh air through the drying machine giving a fresh odor which isl much desired. Thus ozone or other sweetening agents may be 1eifiployed if desired o1 disinfectants or the In Fig. III I show a series of my improved drier units, the discharge 5- being connected to a common conduit 21, the inlets 9 being connected to'a common inlet 22. The stems 23 of the shutters 19 are provided with arms 24 connected by a link 25 for simultaneous operation. This link is controlled from the piston 26, the rod 27 of which is connected to the link V25 by the connecting` link 28.

The passage ofthe actuating fluid to the cylinder is controlled by the valve 29.actu ated by the tappets 30 on the tappet rod 31 carried by the piston rod 27, so that the piston is gradually moved to the left with the parts as in Fig. AIV until the right hand tappet opens the valve which allows the spring 32 to return the piston, the spring v .being mountedv on the `rod 33 proecting from the piston. As the piston is returned the left hand tappet moves the valve to the position shown in Figs. IV and V when the actuating fluid is conducted to the cylinder. The source of supply for the actuating fluid is not illustrated further than the pipe 34.

The laundry is introdueedinA the drying chambers through the doors 35, shown conventionally.

In Fig. VII I show a modification in which the air heating chamber 36 is separate from the drying chamber, coils 37 being arran ed in the air heating chamber between ba es 38 disposed to provide a zig zag passage for the air through thedrying, caslng, the air inlet pipe 39 being controlled by the valve 40. The blower 41 is- 4connected .to

the casing 36 bythe pipe 42 having a valve 43 therein.` A by pass 44 is provided for the air heating chamber, this pipe being controlled by a valve 45 and having connections' 46 for the tanks, as 17,' shown in Fig. I.

The embodiment shown in Figs. I and II is very desirable on account of compactness.

My improved laundry drier is very eilicient in the matter of capacity or volume of work and further, articles dried therein are substantially, without wrinkles and light and fluy, so that ironing is minimized, for

instancea single roll mangle will leave articles dried'by my improved drier in asgood condition as a mangle or ironing machine Icontaining three or more rolls when the articles are dried with the ordinary tumbler drier, and a very great advantage is that the wear on the articles is minimized, there being very little lint or nap worn 0H or diseng ed from the fabric.'

have illustrated and described certain embodiments or adaptations of my improvements which I havedemonstrated to be very practical. I have not attempted to illustrate or describe certain embodimentsor adaptations which might prove desirable and which I contemplate for different installations as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.
